The mage can transform one gaseous
substance into another gaseous
substance, such as turning nerve gas
into harmless oxygen or oxygen into
laughing gas.
Note that this spell does not alter
the dispersion of the gas, just its substance.
Mysterium Rote: Fresh Air
The mages of the Mysterium are
known for crawling into ancient tombs
sealed for ages. This rote allows them
to conjure fresh air into such dusty
places.
